- Renamed netlabel prefixes to accomodate both global
and local store configs.
- Added a `private` marker.
- Skipping the data store configs for remote driver
so that external plugins don't get it as there is
no secure and sane way to coordinate providing
data store access to external plugins.

Add a few bridge network integration tests which
specifically deals with multiple bridge networks
and libnetwork restart and persistence

Remove the need for watching for IPAM data
structures and add multi store support code and
data reorganization to simplify address space
management.

Always on watching of networks and endpoints can
affect scalability of the cluster beyond a few nodes.
Remove pro active watching and watch only the objects
you are interested in.

Add local scope store caching support as
well as do some refactoring to make it datastore
scope aware and manage scope specific config.

Currently the default ipam implementation ignores the prefered ip if the
request is made on an existing sub-pool. The priority should be other
way around.

- When creating the handle, write it to store if
not present. Currently it is written to store
only on first bit allocation.

With the new Discovery model, join can happen even before serf is
initliazed. It could also happen due to misconfiguration of
--cluster-advertise. The local endpoint join must succeed and later when
the serf initializes and joins the cluster, it will push the local db to
the cluster.

With the recently introduced docker discovery, the self node discovery
notification can reach the overlay driver after the remote node
discovery notification. In scenarios such as 2 node setup, it seems more
likely. In those scenarios, the serfJoin is not triggered and hence the
neighborship is not formed between the 2 nodes.
The fix is to retain the knowledge of the neighbor and reuse it
immediately after the serfInit is done. Since we do the serfJoin just
once, there is no harm in changing the neighIP to a new value even if it
is not used.

* integrated hostdiscovery package with the new Docker Discovery
* Integrated hostdiscovery package with libnetwork core
* removed libnetwork_discovery tag
* Introduced driver apis for discovery events
* moved overlay driver to make use of the discovery events
* Using Docker Discovery service.
* Changed integration-tests to make use of the new discovery

- DisableBridgeCreation is misleading. change it to DefaultBridge
- Dont fail the init if localstore cannot be initialized
- added a convenience function to get endpoint for a container

Ideally, both overlay and libnetwork core must be changed to support
kv-store connection retry. But this is a stop-gap measure to unblock the
discovery related PRs.

Replaced it with DisableBridgeCreation and it can be used ONLY in
a special case for docker0 bridge from docker, instead of calling it
from all other case.

This commit adds a basic overlay network
connectivity integration test. By doing this
it adds the basic functions to form a crude
container to run the networking tests. The container
uses a busybox rootfs with network namespace and
/etc/hosts and /etc/resolv.conf generated by
libnetwork.

Currently ther `service ls` output does not show the

Currently on every endpoint Join the /etc/hosts
file is getting overwritten. This blows the already
existing service records. Modify the `updateHostsFile`
function to build the hosts file only on the first
endpoint join and for subsequent joins just update
the existing /etc/hosts file with the additional
network specific service records.
